Windows 2000 Active Directory

Active Directory is Microsoft's answer to Novell's Directory Services. It promises to support a single unified view of all objects on a network (no matter what size) and locating and managing resources faster and easier. Based on the Lightweight Directory Access Protocol, and the Directory Services in Exchange 5.5, this could be a major advance for Microsoft if it works well. A bit of warning to Admin's with no Novell experience - setting up a Directory Tree is no small task and should be planned carefully. A small amount of mismanagement in the early planning phases will be costly later when your network grows.
